Notes:

1. Transceivers are selected as per the availability based on the devices.

2. Requires TX to be enabled. Operation = Simplex TX or Duplex modes only.

3. Requires RX to be enabled. Operation = Simplex RX or Duplex modes only.

4. Option is disabled when receive flow control is disabled.

5. For 100GAUI-2 mode, it is “Include KP4 FEC Transcode” configuration. In this case, the KP4 FEC Transcode within the GTM is used.

6. Block RAM usage for the Statistics counters will be supported in a future release.
